of the five different models own mascaras, this is the second one i have tried. the first was the grow fast mascara which i reviewed here and love love LOVE. i have to say, unfortunately i don't love this mascara as much. personally, i like my lashes to look thick and very black. this waterproof mascara leaves a lot less impact and creates almost wispy lashes.
having said that, it is nice to have a mascara to hand that creates more of a lighter daytime look and i have also started using it over my grow fast mascara as a sort of waterproof top coat. sadly, my reason for doing this isn't because i'm repeatedly jumping in the sea somewhere in the mediterranean, but it does give a bit of extra staying power to the grow fast mascara - much needed in this endless rain the U.K is getting!
the mascara is as waterproof as i'd hope it to be, it can deal with a few splashes so should be fine to swim in but excessive eye rubbing is likely to result in an under eye shadow. i have found it as easy as a non-waterproof mascara to remove with make up remover though which makes life a lot easier.
i think i'd be unlikely to repurchase this mascara as i'm sure there are other options out there that are waterproof and provide the look that i like, but also because i'm such a massive fan of the models own grow fast mascara that i'd be inclined to go for that one instead!
